PATENTED JUNE 4, 1907.

JOSEPH APPLEBY, OF ASTON, ENGLAND SPINNING-FRAME.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed October 26, 1906. Serial No. 340,719.

To all whom, it may concern:

Be it known that I, JOSEPH APPLEBY, a subject of the King of the United Kingdom of Great Britain and Ireland, residing at Aston, in the county of WVarwick, England, have invented certain new and useful Improvements in Spinning-Frames, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relates to .spinning frames and more particularly to the yarn controlling mechanism thereof.

The main object of the invention is to pro vide a yarn controller for spinning frames employing a plurality of finger or guide heads or flaps which are adapted to be raised inclividually or in groups simultaneously, wherein each such head. or flap will be mounted in a support secured to the thread rail or a similar rail positioned below the drawing roller beam, in a manner to prevent said head or flap from working loose through the vibrations thereof, and to minimize such vibrations.

A further object is to provide a yarn controller wherein the guides may be pitched independently of the means supporting the head or flap relative to the rail.

A still further object is to provide a yarn controller of this character wherein each finger head or flap and its support, may be adjusted laterally of the thread rail, or may be removed and replaced without disturbing or removing any other head or flap, thus avoiding a fixed permanent positioning of a number of flaps relative to a thread rail and to each other.

A still further object is to provide a yarn controller wherein the various finger heads or flaps are loosely mounted on individual movable bearings which bearings are adapted to be moved in groups and raise said heads or flaps therewith.

A still further object is to provide a yarn controller employing finger heads of flaps as above described wherein the heads or flaps will be supported independently of the means raising same, whereby there may be movement of said bearings in excess of that required to permit said flaps to come to position above the spindle.

A still further object is to provide ayarn controller of this character wherein the heads or flaps may be both raised and lowered by the bearings.

A still further object is to provide a yarn controller wherein the hinge for the flap will be sufliciently large to minimize the effects of wear thereon, and be so fitted to the bearing as to avoid lateral movement independently thereof.

A still further object is to provide a yarn controller wherein the finger heads or flaps will be so spaced away from the thread rail as to bring the pig tail or other guide into the proper relation to the spindle and permit it to be turned upwardly either singly or in groups, without bringing the guide into engagement with the rollers.

A still further object is to so arrange the heads or flaps and their supports that when raised they will stand substantially vertical, thus facilitating their return to position either individually or in groups.

A still further object is toprovide in a yarn controller, a finger head or flap and a support therefor which will be so constructed and arranged below the roller beam, as to leave an open space below said beam, thus preventing the accumulation of dust and dirt about the hinges on which the heads or flaps are turned in piecing or doffing. And a still further object is to provide a yarn controller wherein the flaps and their supporting means may be inexpensively produced, and in a form which will permit their being conveniently handled both in the-shop and in shipping.

The invention consists in the novel fea tures of construction and combination of parts hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings: Figure 1 is a front view of a part of the thread board of a spinning frame showing a plurality of finger heads or flaps and the supports therefor, embodying my invention Fig. 2 is a plan view thereof with one flap raised; Fig. 3 is a side view of a single flap and its support, and Fig. 4 is a perspective view of a single support with the head or fiap removed.

Like letters refer to like parts throughout the several views.

There are three important types of thread rails and finger guides or flaps in this, art: a Wooden thread rail hinged to the machine and having wooden or metallic flaps hinged thereto by means of an ordinary hinge construction; metallic rails hinged to the machine having blanked hinge sockets formed on the front edge thereof, and metallic flaps having co-operating hinge sockets mounted thereon, and rods mounted in bearings on the machine and having metal flaps loosely mounted thereon, and carrying tappets, or other abutments whereby said flaps are positioned on this rod, supported in the horizontal position, and turned up or raised in groups for'doffing. The first type above re ferred to has the disadvantages that it is more costly than either of the other types; is apt to warp out of shape; is absorbent and thus less cleanly, and is less durable. The second type is more desirable than the old type, but possesses the disadvantage that the position of each flap relative to the thread board and adjoining flaps is fixed by the location of the hinge sockets thereof, and that the long thread boards cannot be conveniently handled. in the shop, are diflicult to make with the desired precision, and cannot be conveniently packed and shipped. In both these types of thread rails the pitch of the flaps is determined in riveting or otherwise attaching them to the machine, the boards and flaps when turned up or raised simultaneously extend to a height which is likely to cause the pig tails or other guides to contact with the rollers, and when horizontal or substantially so catch. and accumulate therethat the bearings. for the rod or shaft upon which the flaps are mounted are spaced apart screws, thus not only making the rod the sole.

on all dust and dirt which falls upon the rail.

The last class, possesses the disadvantages considerably; that the tappets or abutments are not adjustable to permit the lateral movement of the flaps, or if adjustable are secured to the rod or shaft by means of set support for the flaps, but resulting in considerable vibration thereof and of its flaps and a likelihood of the said set screws being loosened thereby. invention shown in the drawings/I obviate these difficulties by mounting each flap on independent bearings adjustably secured to the thread rail and employing a key rod by means of which a plurality of flaps may be simultaneously raised or turned up, and held to any desired pitch irrespective of the means supporting the flaps relative to the thread rai In said drawings, I have indicated the roller beam at a and the thread rail at I) both these parts being as in an ordinary spinning frame. Mounted on this rail 1) are a plurality of flap supports and flaps. Inasmuch as each of these is a duplicate of every other, a detailed description of but one of them will be entered into.

The support for the flap consists of a bracket comprising a base 0 having an elongated slot as c therein whereby it may be adjustably secured to the rail 7) by means of the bolt 0 and forwardly and upwardly projected oppositely disposed parallel arms 01 e.

In the embodiment of my The top of each such arm is circular as at d a forming a way of an arc of a little over 90 degrees. Mounted between the said arms (Z and e and concentric with the ways d e is a tubular sleeve f one side of which is indented or flattened as at f to make what may be termed a D-sleeve thereof. Driven on said D-sleeve or otherwise permanently attached thereto adjacent to the end thereof so as to leave a spindle end adapted torotate in the bearings in the arms at e are cam blanks g h each throughout the greater part thereof being circular and of substantially the same radius as the ways d 6. These blanks are so disposed and distanced from each other that each is caused to bear against the side of its arm d e and thus hold the sleeve f against lateral movement. Each blank 9 it has a projection as g 72/ adapted to engage either side of a finger head or flap, and raise or lower same. The indentation or flattening of the sleeve f will be along a chord of a circle of the diameter of the rest of the sleeve, thus not interfering with the free rotation of said sleeve in its bearings.

Each arm cl 6 has oppositely disposed shoulders d (Z 6 0 disposed at opposite ends of the ways (1 6 respectively, and extending from substantially the horizontal radius of said sleeve f and beyond the vertical radius thereof, which shoulders respectively are adapted to hold the flaps on a substantiallyhorizontal plane, and to prevent their falling back when raised to a point which. would be inconvenient for the operator, when they are raised singly, to turn down a ain.

The finger heads or flaps each comprise a flanged guide support 4) in which a pig tail or other guide 5/ may be mounted or secured in any desired manner. The details of the guide and the means attaching same to.

sides thereof forwardly of said hinge socket I are extended or projected into the path of the projections g h and between the shoulder (1 d e e in a manner to form extensions 7rlc adapted to be engaged by the former and to engage the latter. I preferably employ a continuous hinge socket as described as such entirely incloses the sleeve f and eX- cludes dust and dirt from the hinge or bearing so formed, and it also provides an extended. bearing, thus minimizing w'ear there- A D-rod m or other key rod of the same irregular configuration as the sleeve f is passed through a plurality of said. sleeves and is adapted to be turned therewith by means of a lever m. The end of the rod is provided with a connecting arm as m which is adapted to be connected to a similar connecting arm on the opposite side of a frame in a manner to raise the finger heads or flaps on both sides of the frame simultaneously.

The various parts of the yarn controller are preferably made of pressed metal, such being inexpensive, and are fitted together so as to allow no lostmotion or looseness beyond that necessary to permit the independent movement of the flaps and their sleeves Each flap an d its support is assembled separately,-the hinge socket being fitted over the sleeve f, the cam blanks g h fitted to said sleeve, and the ends of said sleeve projecting beyond said cam blanks forming spindle ends, inserted. in the bearings in the arms (Z 6, said arms being closed up on the blanks g h, holding all parts fairly tightly together. A plurality of these supports and flaps are then mounted on the rail 7) being trued up so as to permit a rod m to be passed through a number of shaftsf.

Each bracket is capable of slight lateral adjustment to properly distance the flaps relative to each other and the spindles, by means of the slot 0 and the bolt 0*.

Under normal conditions, the shoulder (Z (Z will pitch the flaps properly, but if desired the rod m may be used to rotate the several sleevesf to so raise the flaps through the cam blanks g h as to bring them to any desired pitch, the said shoulders or stops d 6 serving to prevent the flaps dropping downward beyond the horizontal.

It will be observed that each flap may be turned upon its socket or hinge upon the sleeve f and raised for piecing or tying, and that a number of such may be raised simultaneously through the rod m in dofhng. I As said rod is turned through the lever m, it rotates all sleeves f through which it passes the projections g h on the several cam blocks engaging the under side of the extensions 7c 7c and raising said flaps respectively until they engage the stop shoulders (1 6 the ways (1 e permitting such movement. The shoulders (Z c in either case will limit the upward throw so as to prevent the flaps passing beyond the vertical radius of the sleeve f to an extent more than enough to permit them to stay up.

hen it 'is desired to lower a single flap, it is merely necessary to throw it forward manually whereupon it will drop to place. After dofling, the direction of rotation of the various sleeves f is reversed to lower the various flaps, such flaps as are not turned through friction between its sleeve f and its loop i, being thrown down by the projections g h engaging the top of the extensions k The circular portion of the cam blanks g h permit the utilization of the projections g h for both raising and lowering the flaps as described.

While shoulders and cam blanks acting on both sides of the flaps are not absolutely necessary to the invention, I prefer to use such as making a more compact and more evenly balanced structure.

It will be observed that there is an open space between the rail 1) and the respective flaps by reason of the forwardly projected bracket arms, thus avoiding an accumulation of dust and dirt about the fiap hinges.

By the construction heretofore described, the vibrations of each finger head or flap, are not transmitted to a long rod supporting a number of such heads or flaps, and are re, duced to a minimum because of the short sleeve f and its brackets, together with the close fit of the several parts of the head and its support.

The various parts of the device excepting the guide are made from sheet metal by press work because this insures accuracy, uniformity and economy in the manufacture of the same, as well as producing an article which will be durable.

It is not my intention to limit the invention to the precise details of construction shown in the drawings and hereinbefore described, it being apparent that suchmay be varied without departing from the spirit and scope of the invention.
